Quite simply put, CSSEdit will save your sanity when editing style sheets. Its intuitive approach to style sheets and powerful editing features will make you deliver beautiful standards-based sites in no time!

superb. this is a fabulous application in every regard, absolutely worth the cost of admission. there's more room for features, which I expect are forthcoming.

I'd like to pick items in preview and have cascade info as well as style defition and stylesheet location, for example --- more of some of the behavior in xylescope, which doesn't have any authoring capability like cssedit.

One of the greatest web dev apps of the moment. It has smart editing features (as in, raw editing), but also provides you with stuff like the revolutionary live preview. Edit your styles locally and it'll show you what will happen, even on dynamic, AJAX-driven sites.
